MINE-CAB WHEEL.

Specification of Letters Patent.

Patented Feb. 3, 1920.

Application filed November 23, 1918. Serial'No. 263,827.

T 0 all 'whom it 'may' concern Be it known that I, LEROY G. BiNxLnY. acitizen of the United States, 'residing at Chicago, in the county ofCook and State of Illinois, have invented certain new and use fulImprovements in Mine-Car Wheels, of which the following is aspecification.

This invention pertains to car wheels and hasty track construction andthe sharpv curves which are present in all mine tracks, it is necessaryto make provision for taking care of the inwardlyT directed end thrustof the wheels and -also to look the wheels against accidentaldisplace-ment off the end of the axle. Various structures have beenproposed to accomplish these purposes and the 'present invention has forits primary object the provision of a structure in which these resultswill besatisfactorily and economically secured.

Instead of having 'the end thrust of the wheels transmitted directlytothe bearing boxes, as has been heretofore done, and instead of lockingthe wheels to the boxes or to the ends of the axle against longitudinaldisplacement from the axle, as has also been customary heretofore, Ihave provided a construction in which the inwardly directed end thrustis transmitted from the inner end of the wheel hub to the axle itselfand I have also provided locking means which locks the inner end of thewheel hubV to the aXle so that it is thereby held against longitudinal'displacement.

Another feature of my invention resides in the provision of strong andsimple locking means whereby the wheel is locked to the axle` whichmeans can be' readily placed in and removed from operative position soas to lock and release the wheel whenever'it' becomes necessaryto do so.

The roller bearing wheel, becausei of the lightness of draft resultingfrom 4its use,

v ventiong is becoming very popular. Some of these wheels have theroller bearings mounted within the hub itself, so that when the wheel isremoved from the axle the rollers remain in the hub. This construction,however, has disadvantages in that the rollers are not accessible forrepairs or replacement. Others have the rollers mounted in cages on thei axle but these cages soon wear out. Still others dispose the rollersloosely between the axle and wheel hub but upon removal of the wheel therollers -fall out upon -the ground.

Another objectv of my` present invention is lto overcome theobjectionable features above mentioned and this, result is accomplishedby the provision of novel means for retaining the rollers in position onthe axle instead of.

in the Wheel hub and without the employment of objectionable cages, sothat when the wheel is removed the rollers remainin position onthe'axle, where they may be readily inspected and repaired or replaced.

Various other objects andinlierent advantages of my invention will bereadily appre ciated as the saine is better understoodv by referencetothe following description when considered in connection with theaccom-A V'panying drawings.

Referring'to the drawingsl Figure 1 is a longitudinal sectional view ofa car wheel mounting embodying my in'- Fig. 2 is an, endelevationlooking toward .i

the left at the construction shown in Fig. le: Fig. 3 is a sideelevation of the construe@ tion shown in Figs. 1 and 2; Y

Fig. 4 is a view similar to Fig. 1 showing another form of my invention;y

Fig. 5 is a similar view showing still another embodiment of myinvention; and

Fig. 6 is a side elevation of the structure vshown in Fig. 5.

Referring to the drawings and particularly Figs. and 3 thereof,reference character 7 indicates v`generally a bearing box for a mine carwhich is adapted to 'be securely attached to the body of the car bybolts which pass upwardly through the openings 8 provided in the web ofthebox toi` that purpose. Within the box there is jour naled the axle 9which extends frohi side to side of the car. and ofcourse projects atits opposite end through a boxl similar to'that. shown in the drawings.It is thought, ho`wever, that an illustration of a box and wheelThiscollaris provided at its inner end `\vith` a radially`projectingflange 1G toriiiing in eli'ect aslioulder on the axle andthis flange drawing the lretainers laterally from their pockets,thusfreeing the wheel so that itcan core or bearing portion 1l of the boxthrough which the axle 9 projects is slightly enlarged toward the centerot' the box, as

indicated b v reference character l2, to receivel` a collarl which maybe rotatably mounted on the axle and held against longitudinal movementor rigidly attached to a reduced,

portion ll of the axle by means of a pin l5, orctherpreferred tasteniiigmeans.

projects outwardly intoithe body et tliebeai-` ingv box and is providedon its inner face y ivithan annulanrib 17 whichseives to liold againstdisplacement the inner ends otl the bearing rollers'lS which areinterposed .be-,i tween-.the axle, and the surrounding hub 19 of the car`Wheel 2l. y

The .finiieigend of the hub ofthe wheel 21 .22 adapted `to abut againstthe flange 1G so that, iinvvard end thrust of the wheel ,is

transmitted through the flange 16 directly'to 'theaxle 9; This ivlieelflange also provides a shoulder and for the purpose of locking theivheel to the axleagainst longitudinal displacement therefrom Iy haveprovided a plurality of` channel-shaped retainers 24 adaptech as shownin Fig. l, to embrace the flanges or shoulders on the ivheel hub and theaxle so that the ivheel is securely locked;` against ,outivard movementivith respect to.

theaxle. 4To accommodate these retainers 2l the sides of the bearing boxare. provided y y; ivith laterally opening pockets 25, as shoivn i inFigs. l and 3 and after the vvliecl has been positioned on the axle theretainers 2l l pockets 25. It will be obvious that the retain ersholdjthe Wheel Aagainst longitudinal displacement from theaxle and thatwhen' it necessaryV to remove the Wheel for any'- purpose it may bereadily accomplished by* fsimply'removing thecotter pins 26 and Withbeslipped ofi the end of the axle.

In Fig. 5 a further modification ofthe inventionzis:disclosedfin thatthe retainers 24, which:aretsubstantially the same as those -are slippedinto the pockets fromthe bottom thereof instead' of from the 1' side.This structure will be clearly evident from Figs. 5 and 6, from which itivill be observed that the retainer pockets are closed at their top andat their sides but areleft open at the bottom to per mit thelongitudinal insertion of the retainers 9.4. After the retainer has beenplaced in position, this bottom is closed by a plate 38 which is securedto the walls of the pocket by lag bolts 39 or other means. It will beevidentthat in this lconstruction the retainer pockets are entirelyclosed so as to exclude the entrance of any dirt or dust into thebearing box. It should also be noted in connection with each of theforms of the invention herein shown that suflicient clearance is leftbetween the retainer and' the end walls of the pockets so that theretainer never comes in contact with these end walls to transmit any ofthe end thrusts or ulls of the. wheel to the bearing box itself, but allthese vthrusts and pulls are transmitted through the shoulder 16directly to the axle so that these strains are distributed between thevtwo bearing boxes instead of coming 'entirelyl upon one box, as occurswhere the wheels are locked directly to the boxes.

It is believed that my invention and many of its inherent advantageswill be readily appreciated from the foregoing wi'tliout furtherdescription; and it shouldbe obvious that the invention is capable ofconsiderable modification and variation in its structural embodimentvwithout departing from the essence of the invention as set forth in thefollowing claims.
